Porsche is OBSESSED with Boxer Engines: Here's Why

[@golfpark94]

Dear Matt, thank you for this very informative video. I drive a 2004 boxster and between you and me; I am the slowest Porsche driver in the world, I just love the engineering of the brand. It all works very well and after 20 years it just does what it is suppose to do, bring a smile to my face.

Not all forces are cancelled. The longitudinal offset between piston pairs do setup a small rocking couple. But as ICE engines go, they are smooth and fast revving, and sound great. I have a 3.4 L Cayman S.

The way Porsche made boxer engines made it look like it's reliable but besides Subaru I don't think that level of boxer engines can be replicated the same

[@DrivenbyMatt]

Good point

[@mjoelnir1899]

The classic VW Beetle has a boxer engine, the VW Bus and the Citroen 2CV. All highly reliable. Porsche cars actually started off with a tuned Beetle engine. You have boxer aircraft engines still manufactured today, again highly reliable.

[@bugnautica-lo9ng]

Subaru is not even close to porsche in terms of reliability unless your a luxury brand that can afford to make everything extremely premium the inherit challenges of this engine will bear there face and cause your engine to explode. Very notable in the WRX and in cars with higher more exposed piston rings that obtain lower emissions but also have a tendency to fail due to inherit exposure to combustion.

[@krisbuck2165]

The Subaru engine can be made reliable with a bit money spent on it look at roger clark motorsports and litchfield as examples

[@bugnautica-lo9ng]

@@krisbuck2165 That is quite expensive and not really worth in in my opinion and a porsche flat six just is reliable.

[@ThatCaymanGuy]

well, for one thing the sound of a flat 6 is pretty amazing. my Cayman is almost 20 years old but it roars when i driving in the canyons on an early Sunday morning. However, it is a big pain in the neck to take the back wheels off the car to change the sparkplugs and coils..

[@DrivenbyMatt]

I’m sure the maintenance is inconvenient, although seemingly worth it. I hope to own one someday. Thanks for sharing, I enjoyed reading.

[@m5pilot397]

How often do you do that, though? Every 60,000 miles?

​@@m5pilot397that and any time you need to get to the side of the engine

[@m5pilot397]

[@williammorris3334]

Porsche also makes their engines durable and they have a life-time cam chain so no timing “belt” to replace. Replace the plugs and drive belt every forty thousand miles and other than typical fluids, brakes, tires and filters that’s all there is on the engine to replace. Another reason they’re so good is refinement. Porsche has been making flat engines for over 80 years. Then there is the intake manifold which is designed to flow air better by using intake air pulses generated when intake valves close and air is redirected to the opposite cylinder bank at increased velocity. They haven’t missed much with so much development.

[@keithad6485]

That was not always the case. with the aircooled motors, the timing chain was a problem with higher mileages, when they stretched to far with wear, catastrophic damage, an after sales fix was implemented, a guide was added against the change which prevented the damage, the other problem was with the K Jetronic. a back fire would see the intake plenum chamber crack due to excessive pressure, lead to uneven running. a spring loaded trap door was added as a precaution, so the plenum chamber had a way to vent the sudden extra air pressure. cured the problem. This was a 1980s fix and it worked well.

[@sc4rf4ce1983]

I bought a Subaru Legacy R Spec B with a 3.0 flat 6 a few years ago. It's such a joy to drive and that smooth flat 6 sound is addictive.

[@JeffDoan-h3e]

Just remembered the Porsche Mooney too. Don't know a lot about it, but was certainly a unique airplane.

[@RoadRunner_RRR]

I worked an Subarus and Porsches. I learned Subaru EJ’s and FB’s were identified as “Boxers” but not Porsches. Porsche engines where know as “Flat” layouts. Boxer engine opposed piston’s share a space on the crank while flat engines (as in Porsches) have their own spaces on the crank.

[@mickmaguire9697]

Ever wonder where the name Boxster came from …..Porsche flat 4s and 6s have always been known as boxer engines !

[@nico_qwer1732]

There has never been a non-boxer flat 4 or 6 engine in a car. The only instance of a flat non-boxer engine in a car is Ferrari's flat 12 engines which were not boxer engine, opposed pistons used the same crank-pin. Yes Porsche calls the engine in the 911 a "flat 6", but it is not a non-boxer flat 6. Its a boxer 6, with opposed pistons having their crank-pins 180 degrees apart which makes opposed pistons go in and out together.

[@Random_User8964]

This. Technically, Porsche's engine is a V6 with the included angle = 180°

[@mardyj]

I think you have this the wrong way around. A boxer engine can’t have pistons sharing a crank pin, because then opposing pistons wouldn’t move towards or away from each other, but in the same direction as each other. Porsches definitely have boxer engines, a 180 degree V would have pistons sharing crank pins and moving in the same direction as each other

[@xtnuser5338]

You've got it backwards. If two opposing piston rods share the same crank journal, it is NOT a boxer. If they each have their own journal, as in both Subarus AND Porsches, then it IS a boxer.

[@johnw.dowding8669]

BEST ENGINE CONFIURATION EVER

[@alshaver3742]

Great video, Matt. Very informative, relevant and concise. The only thing I have to add is what has basically been said below in response to RoadRunner's erroneous post. Flat engines have horizontally opposed pistons. Non boxer flat engines have opposing pistons mounted on the same crank pin resulting in both pistons moving in the same direction resulting in undesirable vibration. The Ferrari non boxer flat engine referred to below was curiously designated by the manufacturer as a "180 Degree V-12". Boxer engines are flat engines in which opposing pistons are mounted on separate and opposing crank pins so that each pair of cylinders moves in opposite directions cancelling out vibrations as stated in the video. Therefore, all boxers are flat, not all flat engines are boxers. All Porsche and Subaru flat engines are boxers.

[@thatguy-m6p]

[@peterj5751]

Great video and well thought out but you missed one other benefit. The inherent balance means that they need minimal counterweights on the crank, meaning they have lower reciprocating mass allowing them to build and lose revs quickly.

[@AutoPilotgogogo]

[@DrivenbyMatt]

Thanks!!

[@MrNorman1956]

I learned to drive on a VW Beetle. Never drove a Porche, but the VW boxer was easy to maintain, and was very reliable. Also as mentioned, great in snow.

[@litestuffllc7249]

As an Owner of a 1971 Porsche 911T which still runs w 1.3 million miles on the original engine I can elaborate on some points. They need near zero maintainence; my carb was set once, after that just sparkplugs - this is due to the high precision and counter balanced forces that you elaborate on. Another aspect you didn't mention is wear - a flat engine starts with oil still in the cylindars; as a result it does burn some oil; but with other engines gravity drains oil so they start nearly dry. Driving the car properly is also key to any cars longevity; keeping in the power range and not lagging your engine is very important.

[@keithad6485]

Which brand of Carb?, sounds like your car had the italian carbies. The German carbies were not as reliable.

[@johnpayne8223]

The rear weight bias helps when braking because there is a significant amount of weight transfer to the front from the rear. The distribution of weight can approach 50/50 under high deceleration.

[@robertvanderlinden2813]

as a volkswagen beetle owner, service is no problem as i can sink the engine out of the engine bay in the matter of minutes and service it on a stand

[@keithad6485]

And very straight forward to disassemble and assemble, if we have the idiot book, I have used the 'Idiot' book to rebuild three flat four beetle engines in the past, each with good long lasting results. Author of the Idiot book, John Muir, may you rest in peace, your book is your lasting legacy!

I have 2 Boxster's, a 2004 manual base, and a 2009 'S' with PDK. Hard to argue against a mid engine flat six in terms of handling dynamics. For driving around town I prefer the manual base 986. It's great fun, and relatively inexpensive. If you're young and just starting out it's a great car to own. Enjoyed the video.

[@m5pilot397]

Absolutely!

[@bugnautica-lo9ng]

911’s less so but 718 cayman and boxter although more so the boxter are very easy to work on they have a large misconception that it is hard to work on them if you have a lift it is effortless you don’t have a big steering rack impeding access from bottom of engine you can get at the front of the engine form the back of your seat where porsche has provided a huge port big enough to service even major things like an alternator and you have excellent side access through wheel wells and you can remove the rear bumper for even more access and there is no radiator there to limit access. The top of the engine can be accessed by putting the convertible roof in service position. The big thing is Porsches reliability these cars depreciate slower than toyotas and refuse to die too so you won’t find yourself needing to work on them almost at all.

Other than oil eating issues with this particular engine, I'm quite happy with the engine and look forward to getting it to 250,000 miles.

burning oil can be an issue. oil can pool in the cylinders due to gravity not being able to pull all the oil down. this can result in an embarrassing puff of smoke upon start up if the car has sat for a long time.

[@timothyharriman2721]

I've always been a fan of Porsche's horizontally opposed engines. However, due to cost-cutting, they have compromised cylinder wall integrity, resulting in a relatively high incidence of bore scoring in later models. This has been slightly mitigated as Porsche moved to a redesigned 9A1 platform. I'm still a fan, but my 3.4L will always need special care before I rebuild it to a 4.0.

[@mr.lumbergh]

[@scottgregory6129]

When I was a kid, I noticed that VW engines (Beetles and Bus) and Porsche engines sounded alike. Soon, Subarus showed up with their funny little cars (yeah, I've been around for awhile) and THEY sounded the same. Once yootube appeared I was learned why. The uneven length of each cylinder's exhaust, the weird squeaky sounds of the fan cooling, etc... anyway, cool video. Thumbs up, new sub.

I love 911s, have one. But the rear engine is a negative, in and of itself, except under braking. Matt didn’t quite explain it fully, but when the weight shifts under hard braking, you’ve got good weight distribution. The engine location works because Porsche has spent decades refining the chassis. Remember the 930? They called them widowmakers because of how they handled under certain conditions. My Cayman technically bangles better, because it’s mid-engines.

Nice video College Matt. In my head I’m a similar age to you, but back here in reality I’ve just started my fifth decade 😲. I’ve been driving boxer engines for around 15 years now, specifically in Subarus (legacy GT models imported from Japan to my home in the UK). They’re great engines for the reasons stated in your videos. I’ve done my own servicing on them for years and whilst my first spark plug change on the flat 4 took 2 hours 😮 I have that down to about 20 mins now. I’ve also owned a porsche, before I started with the subarus so a while back now, but being the 944 turbo that sadly didn’t have the boxer engine. I recently was lucky to spend a few days/300 mile or so trip with my brother in a 992 Turbo including 7 hours behind the wheel in total. That thing is an absolute dream, totally ridiculous speed and such a solid confidence inspiring feeling to drive, or even to sit in as a passenger. It’s made me become a bit obsessed with 911 turbos and while a 992 is waaay out of my budget, I’ve been trying to convince my subconscious that a 997.2 turbo S might be within my reach in a couple of years. Sorry for the rambling, keep up the good work with your videos. your production is good.

[@DrivenbyMatt]

I agree with you, the 991 turbos are spectacular - I hope are able to own one soon. Your spark plug change time is impressive. Thanks for watching and for your comment, I enjoyed reading!

[@1967250s]

I've always understood a boxer to be a horizontal opposed firing order, eg- BMW two cylinder opposed, or 4 cylinder opposed, like the 356 and 912 had. A 6 cylinder engine is not opposed firing order, therefore should not be called a boxer but a flat 6. Not mentioned is that many aviation engines are 4 cylinder, and even 2 cylinder opposed, making them also boxers, and as to more parts? Not really true anymore. Vet, multiple cams, 4, or even 5 valves per cylinder, chains, guides, pumps, etc, all makes of engines, Nissane, Honda's, even American engines, can hqve more parts than a boxer or flat 6. And speaking of: a flat 6 has a very accessible top or underside where most accessories are mounted, unlike v-8s and v-6s where stuff is hidden on the sides that are harder to access.

I ride a BMW motorcycle. With a boxer of course. Smooth as a sowing machine. The servicing is easy, just because the cylinders are so accessible.

There really is no question about the success of the Porsche flat 6. They compete with cars that have engines larger in displacement and still are competitive. The longevity has been proven as the materials used are superior to most. Yes, parts and maintenance are expensive but the performance and longevity of a well maintained flat 6 keeps one smiling.

Boxer type engines provide less bearing load--the weight 9of con rod and cylinders tend to balance out some of the load. Theoretically, this should provide longer crankshaft and bearing life. Most aircraft engines that are air-cooled use this style of engine, or multi-cylinder variants.

[@AIRCOOLEDLIFE]

Hmmm🤔, correct me if I am wrong but I believe the boxster engine is NOT over the rear wheels. They are BEHIND the rear wheels as in the original VW Type 1 layout. ie.....rear mounted engine.

Porsche also perfected the intake manifold so the amount of power they're able to get out of those flat-sixes even before introducing forced induction is always impressive. Porsche also has invested something to the tune of $60 million dollars in research for synthetic gasoline that is carbon neutral, so I wouldn't call internal combustion quits just yet. Wartime Germany in WW2 had been making synthetic gasoline using pea coal because of international embargos and Porsche had designed the gas engines for many of the tanks including the Tiger and King Tiger, so there is precedent for this.

[@DrivenbyMatt]

That would be exciting. Hopefully it happens, I’m holding out hope. I don’t think the complete ev switch will happen as quickly as people think. Lots of infrastructure investment has to occur before EVs are ruling the roads. Anyway, thanks for sharing

To celebrate this achievement we're going to invest a chunk of change into synthetic gasoline because we love the 911 so much"

And yes the flat-6 by definition is a boxer engine. The movement of a boxer's hands is similar to the horizontal movement of the pistons. Porsche calls it a flat-6 since that’s the technical description. Boxer is simply a derived name. Likely made up by auto journalists.

[@chrisdaigle5410]

First, you get a like because you say Porsche more correctly than most others. Usually, I shut off the video the moment I hear the person mangle the man's name.

Taking a V engine and opening it to 180 degree doesn’t make it a boxer engine. The difference is in the crankshaft

[@DrivenbyMatt]

Yes that’s correct. I’ll have to be more explicit in my wordage lol. Thanks for the comment

[@stray1467]

Not to get too technical but i just got a new 718 cayman with a 2l boxer 4, the car is amazing and the engine is a masterpiece of engineering. (Ps: if you are ever able to get a Porsche sports car get it and you wont regret it)

[@DrivenbyMatt]

That sounds incredible, did you get the 6 speed or the PDK? If I ever get my hands on one you'll definitely see it on this channel haha. Thanks for sharing.

[@budthompson2020]

Very informative video, I really enjoyed it. It makes me wonder if the boxer could be coupled with the old timey VW automatic (semi) tranny and coupled with a 356 . . Always wondered that

[@DrivenbyMatt]

Thanks!!

[@m5pilot397]

Only if you wanted to ruin the value of the 356. They are very valuable now.

[@ThinkermanQuindo]

The VW bug employed an air cooled 4 cylinder boxer engine which was magnificent, also in its simplicity, and very reliable, albeit noisy and not so efficient. But it was good enough to be bored out and pairs were used as aircraft engine s by a French company who built light aircraft for use in places like Africa and Australia by flying doctors, among others. Twin boxer engines from BMW were also used to power the original Citroen Deux chevaux in post war France.

[@m5pilot397]

The valve heads used to separate from the stem. Kind of ruins your whole day.

[@robertblahnik]

My bug got me everywhere I wanted to go

[@st-ex8506]

Most light aircraft are powered by flat 4s, 6s, as well as some rather rare 8s. The main reasons for this choice were a) less vibrations (although still quite a lot for the light structure of an airplane), and b) easier to air cool, as you rightly said. Moreover, the problem of difficult access for maintenance, that exists in cars as you stated, does not exist in aircraft, as the engine(s) sit in cowl(s), that can be opened on both sides, or even easily entirely removed in minutes. Although those engines, for Porsche as well as for light aircraft, are designs dating back to the 1930s... so getting very much obsolete. The future is to powerplants MUCH lighter and smaller for a given power, with much flatter power and torque curves to the point of requiring no transmission box, requiring very little cooling, almost noiseless, inducing zero vibration, much cheaper to build, requiring next to zero maintenance over much longer life times. Oh, and BTW, they also require much less (in terms of $) of a different "fuel": electrons!

[@m5pilot397]

The sound of an NA Flat Six is definitely not obsolete. I had a Tesla for five years. I’m pro-EV, but not at the expense of everything else. Horses for courses.

[@st-ex8506]

@@m5pilot397 You need noise to reach satisfaction?!?! For me, noise is rather repulsive, whether it comes from my own car, or even worse, someone else's! I made up with it for decades, like everybody else, and didn't complain as long as they were no alternative... and definitely preferred a good -sounding engine to a bad-sounding one. But now that it is available, I much prefer a quiet ride, possibly with a high-quality rendering of my favorite music. Well, I guess my grand-son also needs his comforter!

[@m5pilot397]

I really feel sorry for you.

[@RideTheLifeQc]

boxers are all right, their lack of mid-long term reliability makes them a bit scary but when its used in a sports car, a bit more tempting...the noise they produce is a bit undewhelming compared to say a 4 cyl honda and the cars they come in is a problem too lol, id love to buy one in a light chassis but they juste dont exist for less money...cool engines !

[@dkjens0705]

Laying a V engine flat makes a 180 degree V engine, such as the 917 engine which was a flat V12 engine, not a boxer engine since each set of opposed pistons shared the same rod journal on the crank. A boxer engine has to have individual rod journals for each piston and opposing pistons have to move in and out at the same time. Porsche doesn't only peoduce wonderful boxer engines, their engineering is much better than other car brands. I'd rather do R&R on ten Porsches with boxer engines than one BMW or Mercedes, Porsche is just that much better thought out and engineered.

[@matheusbastos6429]

I've always wondered, Does the high performance porsches 911 use a Flat or boxer engine? Sometimes it says it's a boxer, sometimes it says it's a flat, I think like the GT3, GT3RS uses Flat engines, but Turbo S, and other more comfortable ones, use Boxer engine, right?

[@DrivenbyMatt]

A flat engine just means the pistons lay flat and horizontally opposed on the opposite side of a central crankshaft. There are two main configurations (that I know of) for a flat engine. One is the boxer engine, and the other is the 180 degree V configuration (think of a V8 stretched to 180 degrees). In a boxer engine, each piston has its own crankpin. In a 180 degree V configuration, the pistons share a crankpin. All of Porsche's flat engines are boxer engines. So the GT3, GT3RS, Turbo S, 718, etc. all have boxer engines (either 4 or 6 cylinder). So in summary, all boxer engines are flat engines, but not all flat engines are boxer engines. Hopefully this helps. Thanks for commenting!

Lookup the Fuhrman 4 cam racing engines of the mid to late 1950's. I had one in a 1954 VW Bug years ago and it hauled a$$!

911's were air cooled until the 996 generation. The 993 was the last air cooled generation.

[@DrivenbyMatt]

Yeah, that’s what I meant but I now see why you say that. I meant “until the 993 generation,” meaning the 993 generation was the last to be air cooled. But I didn’t recognize that it could always be interpreted as exclusive. I’ll try to be more specific w language next time, thats on me. thanks for pointing that out

[@m5pilot397]

No biggie. Through the 993 might have been better verbiage.

Thanks, and I agree. I hope ICEs have plenty of life left so long as people like u and me are around lol. I appreciate the comment

[@jamescaldwell5]

Cool video. But Porsche does not seem quite as devoted to the boxer engine as Subaru. As soon as they put the engine up front in any of their cars, Porsche decided to use inline engines for V engines. IMO, their sedans and SUVs would be much cooler if they had boxer engines. Maybe even some Boxer flat 8 engines.

[@DrivenbyMatt]

You have a good point - I think I might look into it for another video. I could address some of these things. Thanks for the compliment and for the good feedback!

[@richardwood9177]

Boxer engines and a battery (hybrid) make more sense than EV’s. Power to charge the battery. Remember the Chevrolet Corvair. Imagine that nowadays in a hybrid format. A flat 8 in a Corvette wrapped in fibreglass in hybrid form?

[@sugarsaint]

Straight answer, boxer built for rear engine Beatle then the first i 911 used spare Beatle parts including Beatle engine No more no less
